CROWN RUBY against its type

Built in 1997, it is 3 years newer than the median refrigerated cargo carrier on this register, which was built in 1994 (183 vessels with a known build year). At 10,519 gross tonnage it is larger than 57% of the other 178 refrigerated cargo carriers with a recorded tonnage. It is one of 96 refrigerated cargo carriers here under the Bahamas flag, 47.5% of the 202 on the register. The same builder is recorded for 114 other vessels here, 13 of them refrigerated cargo carriers. The returns for 2018–2025 all give Nassau as port of registry.

Its 4,683 t of CO₂ for 2025 is close to the median of 5,190 t among the 111 refrigerated cargo carriers on this register that reported for 2025. Per nautical mile it emitted 258.4 kg CO₂, close to the type median of 260.9 kg. It logged 1,109 hours at sea against a median of 1,731 hours for its type that year. 1.7% of its 2025 emissions were at berth; the median for refrigerated cargo carriers was 3.8%. Across 7 years with reported emissions, the highest was 2020 (11,751 t) and the lowest 2018 (3,963 t). Its efficiency percentile within the type went from 21 in 2018 to 58 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 56 of 95 qualifying refrigerated cargo carriers by EEOI, at the 58th percentile. The dashed line is the type median, 55.3; this vessel reported 57.1.

0255075100more efficientless efficientThis vessel: 58th percentile, EEOI 57.1

EEOI divides emissions by transport work, which for this vessel and year was 82,069,751 tonne-miles over 18,121 nautical miles.

Reported CO₂ in 2025 was 18.2% higher than in 2018, for EU/EEA voyages only.

From 2023 to 2025, emissions rose 6.2% while distance sailed rose 10.4%and CO₂ per nautical mile fell 3.8%.That points mainly to how much the vessel sailed, rather than the other.
